Antipot, for example, has 180-degree rotational symmetry around a vertical axis. It has a second symmetry ... symmetry around the axes going from any vertex to the opposite face.

The coordinates of the turning point and the equation of the line of symmetry can be found by writing ... 3)\) and so the graph will cross the \(x\)-axis at \(x = -1\) and \(x = 3\).

For the parabola \(y=(x+6)(x-4)\) determine the coordinates and nature of its turning pont and the equation of the axis of symmetry. The roots are \(x=-6\) and \(x=4\). The aixs of the symmetry is ...
